Patented Nov. 5, 1935 SLANT ADJUSTMENT FOR LATERAL ARM AWNTNGS 6 Claims.

This invention relates to lateral arm awnings and has for its general object to produce an adjustable hanger and bracket support for lateral arms for the control and adjustment of the pitch or slant of the arm.

One of the objects of the invention is to produce a construction of the type mentioned which is provided with interlocking members whereby the awning bracket may be preliminarily locked to the hanger in its approximate position, and a screw operated mechanism for bringing the hanger to its final position.

Another object of the invention is to provide a construction in which the screw adjusted member and the bracket may he provided with cooperating wedge faces so that they will all be reliably and securely held against vibration when they have been finally adjusted.

A further object of the invention is to provide means whereby there may be an interlocking wedge relationship between the abutting portions of the hanger and the bracket so that the clamping of the latter will reinforce, strengthen and stiffen the former.

With the general objects named in view, and others as will hereinafter appear, the invention consists in certain novel and useful features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawings, in which:-

Figures 1 and 2 are respectively a side elevation and a top plan view of an awning arm having an adjustment embodying the invention.

Figure 3 is an enlarged side elevation of a hanger .and bracket, partially broken away to more clearly disclose parts otherwise hidden.

Figure 4 is a section on the line'IVIV of Figure 3.

Figure 5 is a side elevation of the outer end of the hanger.

Figure 6 is an elevation of the inner face of a clamping plate forming a part of the invention.

Figure 7 is a side elevation of the outer end of a slightly modified hanger and bracket adjustment assembly.

Figure 8 is a section on the line VIII-VIII of Figure 7.

Figure 9 is a side elevation of the construction shown in Figures '7 and 8, with the clamp plate removed from position.

In the said drawings, where like reference characters identify corresponding parts in all of the figures, I represents a front pole of any suitable type, and 2 and 3 respectively indicate the outer and inner arms pivoted together for swinging movement as common in the art. The inner end of the inner arm is pivotally mounted on a bolt 4 carried by a pair of ears 5 formed integrally with an awning bracket 6 which is mounted for ro- 5 tative movement on a horizontal axis to adjust the pitch of the awning arm as will hereinafter appear.

On Sheet 1 of the drawings, a hanger 1 is secured to the building front by bolts 8, the hanger 10 being formed at its outer end with a pair of transverse heads or chambers 9 and I0, connected together by a constricted mouth portion I I. The side edges of the head 9 may be bevelled as at I2 for the greater portion of their length. The front wall of the chamber I0 is provided with a key hole shaped slot, in the form shown, the wider portion of the slot being at I3 and the narrow neck portion extending upwardly therefrom as at I4 (Figures 3 and 4).

.Rotatably adjustable within the chamber 9 is a clamping element I5, said element being provided with a tail piece or arm I6 projecting through the mouth II into the head or chamber I0, and being formed with any suitable threaded means to receive an adjusting bolt Il, provided with a reduced neck I8 and a head I9. The bolt I1 is of such diameter that it may be passed through the opening I3 and threaded into the arm I6. When the end of the bolt abuts the back 7 wall of the chamber I0, the reduced neck I8 (the shoulder between the neck and the threads being rounded to substantially conform to the arc of the head) commences to enter into the narrow slot I l, and it will be evident that when this occurs theelement I5 is rotatably adjusted within the chamber or head 9, it'b'eing impossible for the bolt H to move longitudinally as sucha'ction is prevented through contact at one end and by its shoulder, respectively, with opposite sides of the 40 chamber III. The adjustment of the element I5 is limited by contact of its tail piece IS with opposite sides of the head IE, but even with a small chamber the range of adjustment at the outer end of the awning arm is greatly magnified by a small adjustment of element I5.

In the construction as shown, although not essential, the inner face of the clamping element I5 is formed with two sets of reversely inclined teeth 20 so that it may receive a toothed cone 2| formed integrally with the awning bracket 6, although it is obvious that the equivalent result may be secured by making the cone cylindricalif the wedge relationship is not desired. In practice, the bolt I1 and the clamping element I5 are assembled,

and the bolt is threaded about half way through the tail l6 so that the element can be rotatively adjusted in either direction, depending upon whether the arm is to be raised or lowered. The operator then engages the teeth of the cone 2| with the teeth 20- in the approximate position required for the desired pitch. The final adjustment is then accomplished by rotation of the bolt [1.

In some cases it may prove desirable to interlock the hanger and the bracket for reinforcement of the head of the former, and this may be accomplished by providing the face of the hanger with an inclined wedge portion 22 to enmesh with the portion l2 of the hanger, and the entire assembly is clamped against opposite sides of the hanger by means of a bolt 23 engaging a clamp plate 24 having a wedge portion 25 for fitting the portion l2 on the opposite side of the hanger; Of course, the rotative adjustment of the hanger will be performed, preferably, before the clamp bolt 23 is screwed home.

n Sheet 2 of the drawings, a modified structure is shown, in which: the hanger 26 is formed at its outer end with a head or chamber 21 which has communication with a second head or chamber 28. transverse opening 29 in the web of the hanger, and journaled or swivelled, but having no rocking or longitudinal movement, in the front and rear walls of the head 28 is a threaded screw element or bolt 30. The lower end of the arm IS, in this construction may be bifurcated as at 3| to receive a nut or collar 32 threaded on the swivelled bolt 39 and provided with a pair of projecting studs or arms 33 received within elongated sockets or openings 34 in the adjacent faces of the fork 3|. It will be evident that as bolt 30 is rotated, it will thrust in one direction or the other against the hanger and at the same time, but in the opposite direction will apply force to the collar 32 to efiect its travel back and forth to rotatively adjust the clamp element [5. The resultant oscillation of the tail I6 is accommodated by the elongated sockets 34. In other respects, the mode of operation and construction of this modified structure may be similar tothat hereinbefore described.

From the above description, it will be apparent that while I have described the preferred embodiments of the invention, it is to be understood that I reserve the right to make all changes within the spirit of the invention and without the ambit of the prior art.

I claim:-

1. In an awning, a hanger having at one end means for attaching it to a wall and at its other end carrying a bracket for rotative adjustment about a pivot having its axis passing through the hanger adjacent its outer end, means for angu- Rearwardly of the head 28 is a small,
